Rattling works and is used more as a blind call. Grunting works better than rattling but grunting is a call u use when u see a buck to far out and it's working now I have grunted in several deer in the last 2 days its working and when I do hit the horns together I throw in a few grunts and I always hit them with a snort weeze and a few grunts befor I hit the horns. Scents..... Tough topic I guess it's all kinda opinion or trial and error I guess. It deffenitly doesn't scare the deer away but I think like 80% of the time they walk past it and show it no mind that's my input on it
